Watford winger Isaac Success has been absent from the past two match-day squads due to an issue with his knee.

The winger missed more than two months of the season with a knee injury, before returning to the bench at Burnley and taking his place there again at Crystal Palace.

He was a surprise omission from the squad last week and again today. Rumours of a potential departure have surfaced in recents and social media was awash with chat that it could signal a move was imminent.

Marco Silva, however, confirmed he was just having problems with his knee after his time out injured.

As well as Success, Will Hughes is highly unlikely to return on Boxing Day against Leicester City. Silva said a surprise return could be in line on Thursday, but that has not materialised.
